For some applications, for example in vehicles or battery operated applications, an output signal is required which can be operated at low power to enable a long service life. Normally, ratiometric signals are transmitted as 10 ... 90 % of the powersupply voltage. …
In Europe plants or machines used in hazardous areas must comply with the ATEX directive 94/9/EC. Therefore, the pressure sensors or other measuring instruments approved according to ATEX must be used only in conjunction with ATEX approved isolated barriers if they use …
When using pressure sensors and pressure transmitters, our customers often ask for explanations of frequently used terms and abbreviations in connection with "SIL applications". SIL – which means Safety Integrity Level, and PL, which means Performance Level, are …
In my last article, the design of a submersible pressure transmitter / level probe - Part 1, I was explaining the design of a submersible pressure transmitter, beginning with the measuring cell and its electronics. Specifically with respect to the media resistance …
How does the IO-Link communication interface of WIKA's pressure switch PSD-30 actually work? IO-Link is a point-to-point connection (i.e. not a new field bus) between sensor/actuator and a field bus master such as a PLC. The supply of the field device (pin 1 and …
